Evaluation of ceftiofur sodium as a chemotherapeutic agent in grass carp (Ctenopharyngodon idella)
Ceftiofur sodium, a third generation cephalosporin, was studied to determine the potential of this drug as an alternative bacterial therapeutic agent for the aquaculture and ornamental fish industry. Grass carp, Ctenopharyngodon idella have been selected as the fish model for this study since they …

The Effect of Thermophilic Anaerobic Digestion on Ceftiofur and Antibiotic Resistant Gene Concentrations in Dairy Manure
… most of their bioactivity after excretion. Ceftiofur is a commonly used cephalosporin drug but no previous study investigating the effect of Ceftiofur on biomethane during continuous anaerobic digestion has been performed. The aim of this study was to examine the effect on biomethane …

The Impact of Ceftiofur Removal on Recovery of Salmonella enterica and Escherichia coli Resistant to Third Generation Cephalosporins
<p>Ceftiofur use in animal agriculture has been disputed due to the concern over the impact it may be having on the spread of resistance genes among foodborne pathogens. Several attempts to restrict the extra label use of ceftiofur have resulted in failure until the recent FDA ban. No study has …

Metagenomic Analysis of Antibiotic Resistance Genes in the Fecal Microbiome Following Therapeutic and Prophylactic Antibiotic Administration in Dairy Cows
… four antibiotic treatments: control, pirlimycin, ceftiofur, or cephapirin. Fecal samples were collected on d -1, 1, 3, 5, 7, 14, 21, and 28. Samples were freeze-dried and subjected to DNA extraction followed by Illumina paired-end HiSeq sequencing and quantitative polymerase chain reaction (qPCR). …

Effect of a Fermented Yeast Product on the Gastrointestinal Tract Microbial Diversity of Weaned Pigs Challenged With Salmonella Enterica Typhimurium Dt104
… Salmonella and treatment of the piglets with ceftiofur-HCl resulted in alterations to the species richness and abundance of key members of the GIT community. The addition of XPC to the diets of weaning pigs results in greater compensatory gains after infection with Salmonella and an increase …
